This is because it is expected that **your users** would define the actual **URL path** where they want to receive the webhook request in some other way (e.g. a web dashboard).

### Check the docs { #check-the-docs }

Now you can start your app and go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

Run the server and go to the docs: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

You'll see the user interface like:

      // boolean condition2 = nodeU().equals(other.nodeV()) && nodeV().equals(other.nodeU());
      // return condition1 || condition2;
      if (nodeU().equals(other.nodeU())) { // check condition1
        // Here's the tricky bit. We don't have to explicitly check for condition2 in this case.
        // Why? The second half of condition2 requires that nodeV equals other.nodeU.

위의 예시에서, `item_id`는 `int`로 선언되었습니다.

/// check | 확인

이 기능은 함수 내에서 오류 검사, 자동완성 등의 편집기 기능을 활용할 수 있게 해줍니다.
